Application filed February 29 1909.

To all whom it may concern:

1.9 it known that I, lums 0. iii-ms a citizen of the United States,residing at i iaseca in the county of Nose ca and S sic of Minnosota,have invented ccriiiin 11cc and useful Improvements inCounicrbaiai'icing Devices for ain es of which the following isspccification. v

This invention miatcs in general, to pumps of the reciprocating pistonvariety, and more psrticuiui'iy to pumps which are used on i'aiii'ns,either by hand or Windmill i3OWe1 to raise Water for general purposes;unci iis objcci is LO provide means for counterbalancing the weight ofthe movable parts comprising the piston, iis rod, and a portion of theweight of the water so that the ogcrstion will be rendered very lightand cow.

To this end H3." invention con is in the construction ami coiiibinaiionof parts fonn ing'a pump hereinafter more fully described andparticularly sci forth in iiicwiz im crence being bad to thoaccompanying drawings in which Figure 1, represents a perspective Viewof the hand gimp according to my invention. Fig. 2, is a top View of thestationary springplatc. Fig. 3, is a View of the body of the same plotsinvcrtc. Fig. i, is El View of the i'ci'novabic portion of the someplcio iii-- vcrtcd.

Let nu ism}, 8, i'opi'csoni the body of a, pump Stud mi. by brace 9, andprovided with s soon: 10 a haiuiie 11, and rod 2 A brac pivoicci the todis or cud I up and poi-no; zi'ifiziciiii crook s; scl'iwi in the pumphandle so that each plate could be slipped on to the end of lhe rod.This is a matter of great inconvenience, and especially so, when hepistoim'oii is alsoconmooted Wii'h a. windmill. To wabic ihesc plates tobe put. in place wii'houi disconnecting any part of the pumpotfachmcnts, I make each plate in two or more parts, 'ct these plaicecannot be (illpiifffidfs of each OililGll for the plate if); must befastened to {he piston-rod and 01m the pisiommd to play freely throughii, To iiiis end, each piste is moo-o open iii] one cdgc and a removableprovided to close Y itZ1 that opcning. 'iiie plate 18, mmc recesses 21,in iis under side ihc opening aiiii ihc cios which Fla-mimic to iii that0pc; vidci Wiih lugs 24. to rest tho plate iii (ho recesses 21. is to bepiacoci around the p of the poop; ti n it is to boi-cis-ii. a little andthe ciosi gpiece 23, is to be inserted undci it into dis opening withits lugs 24, engaging the apcriurcs 3}, when the plate is permitted torest upoii the pump. The pisiomrod will now ho iii ccioiiing which islarg cnom-l ii- 50 play freely iiicrcnj ii-o pixie 19, has :12; open loiwwcii'c iiw is pro-' engage- )iatc 18, "(i on top mm 29., in row i.ltcsc zc rcvoive. he neck and i'Hf-Lifi 1o ii-mom iiic boii iroiai insci'zawrui c ao-n His 25 .0 pinto ii is sic 18} must permit Q eases?service on both round and fiat piston-rods, l the claims either the capof the pun-i"; or the the apertures 25, 26, are made to fit near enoughfor practical purposes to both forms; and the clamping jaw 28, is madefiat on one face 32, and concave at 33, on the other face. In\ servicethe plate 18, being held firmly down upon the pump top by means of thesprings, holds its closing piece 23, securely under it by means of thelugs 24:, resting in the apertures 21; and the upward pressme againstplate 19, is resisted by the jaw clamped firmly upon the piston-rod 12 lt will be readily seen that, these plates thus adapted to be applied tothe pump rod and to be removed therefrom Without disconnecting any partof thepump, is a matter of great convenience,especially to the salesmanin introducing these counterlmlancing springs for use upon pumps thatare already in service; because the plates may be applied and adjustedto counterbalance the springs so that their value may be shown in a fewminutes. It Will be seen that when the piston-rod 12, projects'farenough above top of the bracket 13 may be termed the tsp of the pump.course it may necessary to furnish springs of different sizes and dif-'ferent degrees of strength for large and small pumps but the plates aseommonly furnished are adapted for nearly the whole range of commonpumps.

Having thus fully described my invent on, what l: believe to be new anddesire to cure by Letters Patent, is the tollewiing:

In a pump, a reciprocating rod and eountel-balancing springs therefor;two plates for attaching these springs to the pump body; one of theplates being secured firmly upon the rod and the other plate restingupon a fixed. portion of the pump, this plate being open at one edge andhaving apertures in. its under side, and a closing piece fitted to theopening andv having lugs fitter to engage the said. apertures in. theplate.

In testimony whereof I Hill my signature in presence of two witnesses.
